or material of a similar nature, which may or may not be covered with a mineral surfacing.

@ne object of my invention is to provide in a shingle strip having gutters, side walls for the gutters projecting above the face of the shingle strip, to prevent water beating in laterally under the shingles along the gutter.

Another object of my invention is to provide in a shingle strip means for giving a heavy appearance to the lower half of the shingle strip.

Another object of my invention is to provide in a shingle strip reinforcements for the lower half of the shingle strip.

Another object of my invention is to provide in a shingle strip reinforcement in the lower half of the shingle strip that will butt against the lower edge of the next shingle strip above, thus stifiening the lower half of the shingle strip against the lifting of the wind.

With these and incidental objects in view the invention consists of certain novel features of construction and combination of parts, the essential elements of which are hereinafter described with refernece to the drawing which accompanies and forms a part of this specification.

In the drawing Figure 1 is a plan view of two shingle strips embodying my invention,-

one superimposed upon the other. Fig. 2 is a front elevation of the two shingle strips shown in Fig. 1, while Fig. 3 is a section taken on the line A A, Fig. 1, and Fig. A is a perspective view of a strip of roofing material showing the development of the shin-" gle strips shown in Figs. 1 and 2.

The strip of roofing material 1, Fig. 4, is sheared along the lines 2 and 3 at equal distances throughout the strip, the surfacing material with which the remainder of the strip is covered having been removed or omitted on the surface between the lines 3, 4: anolli.

'llhe underside of the shingle strip is pref- Speclfication of Letters "Patent.

arably scored along the lines A and 5 baclr to the line 3 at each point where the gutters are to be formed, allowing the material of the folds 6 and l to be bent upwardly at 5...

right angles, and then bent down squarely against the surface of the strip 8 and it, the tackiness of the water-proofing material. in the strip securely binding the folds f3 and 7 squarely to the upper surface of the shingle strip.

The folds 6 and 7 as they are shown at 8 and 9, and also shown in Figs. 1 and 2 in the completed shingle strips serve as longitudinal reinforcements for the lower half of the shin gle strip, and as in mineral surfaced shingles the upper surface of these folds would be black, while the gutter would show the color of the mineral surface of the shingle strip below, the result is a heavy pleasing effect when laid upon a roof in shingle fashion.

The shoulders formed by the folds at 3 serve as a guide for laying the shingle strip 7 above, and as these are raised above the surface of the shingle strip no care is needed to aline shingle strips of this construction, as they will naturally seat themselves against the shoulders at the point 3. Furthermore, as the shoulders 3 of the folds butt tightly against the lower edge of the shingle strip above, the reinforcement produced by the folds is extended to the lower edge of the shingle strip above, and hence the lower half of the shingle strip is strengthened throu hout against being lifted by the wind.

As the strips are laid upon a roof in shingle fashion, it is evident that any water that is blown diagonally or transversely across the roof will be dammed up by the folds constituting the reinforcement, and not blown into the gutter, and asthe reinforcement is higher than the surface a certain amount of protection is also afforded against the beating of the rain into the gutter, hence there is less possibility for rain to be driven under shingles of this type than of, the side edges of said tabs being thicktabs being reinforced by bending the porened to reinforce the tab, and forming a tions described by the slitting, back upon channel or gutter between the thickened the upper surface of the tab forming a gut- 5 portions. ter, and the upper end of said turned back 2. A roofing strip having shingle-like tabs portion forming a gage line for laying the formed throughout the lower ortion thereof superimposed strip. by a T shaped slit, the side edges of the tabs 4.
